对30例泌尿系结石病人进行体外震波碎石治疗前后进行心脏收缩的间间期(S7I)测定,结果显示心率(HR)显看减慢,电机械收缩时间(EMT)、左室射血时间(LVET)、射血前期(PEP)、心脏机械收缩时间(MST)均明显延长,对其它指标无明显影响。我们认为体外震波碎石治疗能延长心脏收缩时间,加强泵血功能。
The measurement of interictal systole (S7I) before and after the extracorporeal shock wave lithotripsy in 30 patients with urolithiasis showed that the heart rate (HR) showed slowed down, electromechanical contraction time (EMT), left ventricular ejection time LVET, PEP and MST were significantly prolonged and had no significant effect on other parameters. We believe that extracorporeal shock wave lithotripsy can prolong the time of cardiac contractions and enhance the blood pumping function.
